PM Update: Showers, sometimes heavy, into Wednesday then clearing

Our second straight day of a serious lack of sunlight has passed. Maybe by Wednesday afternoon, some blue skies emerge. But clouds prevail tonight, and heavier showers and thunderstorms arrive by morning. And even as partial clearing occurs during Wednesday, we won’t be able to totally shake the rain threat until dark.

Through Tonight: The warm front which produced today’s rainfall has lifted to the north, shutting off shower activity south and west of D.C. The rain will take a break in the northern suburbs by mid-evening too. But towards pre-dawn, a cold front will approach bringing showers and possible thunderstorms. Temperatures are steady or even rise a bit overnight, generally in the mid-to-upper 50s.

Wednesday: You’re likely to awake to showers and possible thunderstorms. We can’t even rule out some gusty winds accompanying this activity, which should move through pretty quickly. By mid-to-late morning, skies may brighten or even partially clear. However, during the afternoon, a disturbance moving through aloft may trigger a few more showers. Temperature don’t do a lot: possible sunshine offsets any cooling behind the front, so highs should reach into the low-to-mid 60s.
